The attackers, Morgan Geyser and Anissa Weier, were 12 years old when they lured another 12-year-old, Payton Leutner, to a wooded area in a park near their home in Waukesha, Wisconsin. They allegedly stabbed her 19 times and left her there to die.

Doctors said one of the stab wounds narrowly missed a major artery.

The girls allegedly plotted the attack for months, according to the report.

RAGE AT RAPIST'S AID

Payton miraculously survived the attack despite wounds to the chest, abdomen, and arms.

She crawled from the wooded area where she was stabbed and was found along a road, bleeding from 19 stab wounds that nearly killed her

The crime was reportedly an attempted sacrifice to Slender Man, a fictional horror character that is described as a demon-like, tall, lanky figure without facial features who lives in a mansion in the forest.

The girls told investigators they were walking 300 miles to a national forest where they hoped to live with Slender Man as servants in his mansion, according to Fox News.

Anissa suffers from a delusional disorder and a condition known as schizotypy

Experts testified that one of the girls has schizophrenia and an oppositional defiant disorder that requires long-term mental health treatment.

The other girl has been diagnosed with a delusional disorder and a condition known as schizotypy, which a psychologist testified made her vulnerable to believing in Slender Man.

In the ruling on Wednesday, the Second District Court of Appeals said it was reasonable to try the girls as adults because the juvenile system could see them released at age 18 with no supervision or mental health treatment.

Given the serious nature of the offence, given the crime was both planned out and violent, the appeals court ruled it would be inappropriate for the trail to take place in juvenile court.

However, the girls and their families and attorneys can appeal the ruling to the Wisconsin Supreme Court.

Who is the Slender Man?

SLENDER Man is a sinister online myth which the girls are said to have believed in.

It is a fictional supernatural character that originated as an Internet meme created by Something Awful forums user Eric Knudsen
It is depicted as resembling a thin, unnaturally tall man with a blank and usually featureless face, wearing a black suit.
He is said to stalk and abduct children and has tentacle-like arms which can be used to capture prey.
